The SN65HVD23D is a RS-485 Extended Common-mode Transceiver for use with electrical power inverters. The transceiver in the HVD2x family offer performance far exceeding typical RS-485 devices. In addition to meeting all requirements of the TIA/EIA-485-A standard, the HVD2x family operates over an extended range of common-mode voltage and has features such as high ESD protection, wide receiver hysteresis and failsafe operation. This family of devices is ideally suited for long-cable networks and other applications where the environment is too harsh for ordinary transceivers. This device is designed for bidirectional data transmission on multipoint twisted-pair cables. Example applications are digital motor controllers, remote sensors and terminals. This device combines a 3-state differential driver and a differential receiver, which operate from a single 5V power supply.
● Common-mode voltage range (-20 to 25V) more than doubles TIA/EIA-485 requirement
● Reduced unit-load for up to 256 nodes
● Bus I/O protection to over 16kV HBM
● Failsafe receiver (bus open, bus shorted and bus idle)
● Receiver equalization extends cable length, signalling rate
● 1µA Maximum low standby supply current
● More than 100mV receiver hysteresis
● 25Mbps Maximum signalling rate
● Green product and no Sb/Br
